Remove the HVAC console by removing the 2 screws below and then push down on top to release the securing 2 tabs.
Pull the 5 pin plug shown below.
The terminal which had the plain green wire is the feed, positive with the ignition on.
Using a short jumper wire from this positive terminal, touch the other end to the other three terminals which are the 3 speeds;
1) Terminal that had the Green/Blue wire attached (speed 1)
2) Green/SlateGrey 2
3) Green/Yellow 3

If all three speeds do not work you have a Resistor pack defect.
If all three speeds do work you have a 3 speed switch problem.
